Low frequency wind turbines are a complete set of technical equipment specifically developed for flexible low-frequency transmission technology. They are a new form of wind turbine power supply that can directly output 20Hz low-frequency AC power through a full power converter, meeting the power side requirements of flexible low-frequency transmission technology. In low-frequency scenarios, the grid friendly control effects of fault traversal, reactive power/voltage control, power quality, and harmonic suppression on the grid side of wind turbines have all changed, and the testing indicators and methods are different from those of power frequency wind turbines.
